SUPPORTING MEANS OR BRACKET FOR LAMPS.

SPECIFICATION forming part of Letters Patent No. 595,074, dated December7, 1897.

Application filed September 21, 1896. Serial No. 606,518. (No model.)

T0 in whom it may concern.-

Be it known that I, REINHART W. PITT- MAN, a citizen of the UnitedStates, residing in Hartford, in the county of Hartford and State ofConnecticut, have invented certain new and useful Improvements inSupporting Means or Brackets for Lamps, of which the following is aspecification.

This invention relates to means orbraekets for supporting lamps, and ismore particularly designated as a pendulous or suspension lamp bracketor support, and is more especially adapted for carrying or supportingincandescent lamps; and the object of the invention is to provide animproved universally-adjustable supporting means simple in itsconstruction and operation and which will also be pleasing, neat, andornamental in appearance.

A further object of the invention is to provide a lamp-supporting meansadapted to be suspended from a ceiling or other suitable place and bymeans of which the lamp supported thereby will have a universaladjustment to permit it to be adjusted into any desired position withincertain determinate limits dependent upon mere mechanical construction,whereby the lamp may have an adjustment transverselyto and into anydesired lateral position relatively to its vertical or penduloussupporting means without changing the position of such supporting means,an adjustment in a circular horizontal path relatively to saidsupporting means without exerting torsional stress or twisting orturning of such supporting means, an adjustment in a circular pathtransversely to the plane of its circular horizontal path, and avertical or an up-and-down adjustment relatively to its supportingmeans.

A further object of the invention is to provide an improved supportingmeans which will permit the lamp to be adjusted or swung into variouspositions independently of the adjustment of the supporting meansproper.

In the drawings accompanying and forming part of this specification,Figure 1 is a View of one form of thisimproved supporting means orbracket, showing a part of the main weight thereof in section andshowing the supplemental weight in its normal inoperative position. Fig.2 is a view of this improved supporting means, showing the lateral ortransverse adjustment of the lampholding means or red and also theadjustment of the main weight relatively to the perpendicular orpendulous supporting means to equalize the weight of the lamp in itsadjusted position, said view also showing another means of car- 'ryingan incandescent-light globe, such globe being shown in dotted lines.Fig. 3 is a longitudinal sectional view of a portion of one form of mainweight, illustrating more clearly the means for securing or clamping thelampholding member or rod therein. Fig. at is a view similar to Fig. 1,showing this improved supporting means carrying an incandescentlightlamp having a shade thereon and showing the supplemental weight adjustedin position to equalize the increased weight of the lamp with its shadeand also showing in dotted lines the positions of the lamp and shadewhen the supplemental weight is adjusted inwardly or toward thependulous supporting means. Fig. 5 is a view of another form of main andsupplemental weights. Fig. 6 is also another form of main weight withthe supplemental weight adjusted into a different position from thatshown in Fig. 5. Fig. 7 is a view of one member of one form ofsuspension or supporting means with one construction of coupling devicesecured thereto. Fig. 8 is a view thereof taken at right angles thereto.Fig. 9 is a view of the lamp-carrying means or member, partly insection. Fig. 10 is a view thereof taken at right angles thereto. Fig.11 is a view of one means or device for securing the penduloussupporting member in position to a ceiling. Fig. 12 is an edge viewthereof. Fig. 13 is a view of this improved supporting means, showinganother form of weight and showing the lamp adjusted with its bulbextending upward. the vertical or upward adjustment of this improvedsupporting means with the weight broken oft. Fig. 15 is a view ofanother form of the character of weight shown in Fig. 13. Fig. 16 is aview of one form of means for supporting an incandescent lamp similar tothat described in connection with Fig. 2, a portion of such incandescentlamp being shown in dotted lines, and said view also showing the meansof adjustment whereby the lamp may be swung outwardly or up wardly; andFig. 17, Sheet 1, is a view Show Fig. 14 is a view showing in a generalway by B and carried or supported by said suppporting or suspensionmeans,) said weight embodying means of adjustment whereby the lamp maybe adjusted into different positions, and said weight in one formthereof also embodying a supplemental weight whereby different sizes andweights of lamps may be supported, and in the same or in another formthereof embodying a supplemental adjustment whereby also differentWeights and sizes of lamps may be supported, and laterally ortransversely adj ustable lamp holding or carrying means, (designated ina general way by O.)

In the preferred form thereof herein shown and described the weightsupporting or suspension means A comprises a pendulous member, such as arod or bar 18'of'any suitable materialsuch, for instance, as wire andpreferably adapted to resist torsional or twisting movement, and whichsupporting member is preferably composed of two members, one of which,as 19, comprises a series of short bars or members 20 21, whereby saidsupporting member may be made of any desired length by coupling two ormore of the members together by any suitable means, such as aclamp-sleeve 22 and a clamping device or screw 23, and thus permit anydesired length ofpendulous supporting means to be quickly made withoutthe necessity of using one length of rod or wire. It is obvious that twoor more of these bars or members could have relatively long overlappingends or portions, as shown in Fig. 1 of the drawings, whereby suchsuspension member could be lengthened or shortened and thereby adjustedas found necessary for different heights of ceilings by decreasing orincreasing respectively such overlapping parts or ends. The other memberof this supporting means comprises a member adjustable relatively to themember 19, and in its preferred form comprises a sleeve 24, splitadjacent to its upper end and havinga collar or clamping-band encirclingthe same, and carrying a fastening or clamping device, such as aset-screw. 26, and into which sleeve 24 apart of the member 19 extends,whereby the Weight can be adjusted up and down and clamped in anydesired position by the clamping device 26.

It will be understood, however, that the; members 19 and 24 of thissupporting means might be held in position relatively to each other byany other suitable means, if desired, in place of the clamping-sleeve 25and setscrew 26.

It Will also be understood that the incandescent-light conductor or cord80 might be used in place of the member 19 as one member of thesupporting means A by simply carrying the same through the sleeve 24,from the top thereof, and out through an opening 2r at the side of suchsleeve 24-. adjacent to the bottom, whereby the sleeve could be adjustedon the cord. (See Fig. 17.)

Any suitable means may be used for securing this weight-supportingmember A in position toaceiling or wall. One form of means herein showncomprises a suitable block 28, having a central perforation 29 and atransverse recess 30 on one face of said block open in g into saidperforation and at the periphery thereof and adapted to receive a bentend of the supporting member A, Figs. 1 and 14. This block 28 may besecured to the ceiling or wall by any suitable means, such as screws 31,for which purpose the block is provided with perforations 32.

It will be understood that any desired construction and form of weightadapted for the purpose may be used, but according to one form thereofherein shown and described the weight is provided with suitable meansfor carrying a transversely-adjustable lamp holding or carrying means 0,hereinafter described, and with a suitable supplemental and adjustableweight whereby the effectiveness or efficiency of the main weight can beaugmented or increased, and in one form thereof suitable means wherebythe main weight can be adjusted to increase or augment the effectivenessor efficiency of such supplemental weight, or vice versa.

In one form of bracket shown the weight is illustrated asquarter-moon-shaped or semicircular, from which it will be obvious thatits own weight can be augmented by reversing its position relatively tothe suspension memberthat is to say, by turning the weight so that thesemicircular part'thereof will be relatively remote from said suspensionmember its weight will be augmented as compared therewith when in theposition herein illustrated.

In the preferred form thereof herein shown and described the main weight34 is preferably heavier than the ordinary form of lamp to besupported-such, for instance, as an incandescent-light lamp 100and isprovided with a suitable supplemental weight 35, adjustable on said mainweight to augment or increase its eifectiveness or efficiency. The mainweight 34 is also provided with suitable means for carrying the lampholding or carrying means and is herein shown having a longitudinalaperture or bore 36, adapted to receive said lamp holding or carryingmeans 0, and which bore in the form of weight herein shown extendsthrough a substantially circular portion 37 thereof. The supplementalweight is provided with a suitable clamping device-such, for instance,as a set-screw 1 38whereby it can be clamped in position on said mainweight in any desired place within the limits of its adjustment, and forthis purpose the main weight 3i is provided with a way 39 and thesupplemental weight is provided with a groove or slot adapted to slideon said way 30, whereby the supplemental weight can be moved intovarious positions to increase or augment in different degrees theeffectiveness of the main weight. It will be obvious, however, that themain weight might have the recess and the supplemental weight slidetherein, if desired, it not being deemed necessary to herein illustratesuch a mere mechanical change.

According to one form of means for securing the weight B in positionrelatively to the pendulous supporting means A, said supporting means isprovided with a coupling, which may be of any suitable constructionadapted to permit circular movement of the weight and the lamp carriedthereby. In the preferred form thereof, however, this coupling 40, Figs.7 and 8, comprises a suitable bifurcated bracket or ll-shaped angle-iron+tl, having an upwardly-extending stud or pin 42, 011 which said bracketor angle-iron turns, and which pin or stud 42 has suitable screw threadsadapted to enter a threaded aperture a3 in the lower end of the sleeve24:. A spiral or coiled spring at is interposed between the lower end ofthe supporting-sleeve 2i and the bracket 41 whereby said bracket isprevented from free rotary movement relatively to said sleeve andsupporting member. A transversely-extending pin or journal 45 projectsthrough the arms of the bracket and constitutes a means for directlysupporting the weight or the weight-bar or arm, as the case may be. Thisweight-bar or arm 46 in one form thereof is adapted to slide on said pinor journal 4-5 transversely of the supporting means A and is operativelyconnected to the main weight, and has an enlarged end 47, or othermeans, whereby it is prevented from detachment from the coupling, andsaid bar or arm 46 maybe detachably connected to the main weight and mayconsist of a plain bar i8, Figs. 1 and 4, or be provided with a rack 49,Fig. 5, or said bar or arm may be integrally joined at both ends thereofto the main weight and be plain or be provided with a rack it), Fig. 6,or said bar or arm may be constructed in the nature of a rack-bar or arml0 integrally joined to the weight at one end thereof only, Fig. 13, sothat the bar may constitute directly or indirectly a part of saidweight, as desired. This bar AC6, which, as before stated, may havearack or a plain face, supports the weight, and in the preferredconstruction said weight is adjustable on said bar toward and from theweightsupporting means A independently of the adjustment of the bar it,and in one form thereof this adjustment is obtained by providing theweight with a suitable sleeve 50, having a clamping device in the natureof a set-screw 51, whereby the weight may be adjusted on the bar to andfrom said weightsupporting means A and clamped in any desired position.

The lamp holding or carrying means proper, C, preferably comprises twomembers, one adjustable relatively to the other and both adjustablerelatively to the weight, and in its preferred form this lamp carryingmeans preferably comprises a tubular sleeve 60, having alongitudinally-extending slot 61, Figs. 9 and 10, at one side thereof,and which sleeve extends transversely through the bore 30 of the weightB, whereby it will also extend transversely to or from the supporting orsuspension means A, according to the position of the weight, and isadjustable transversely of said weight and clamped in any desiredposition by means of a suitable clamping device in the nature of aset-screw 62. This sleeve may be provided, if desired, at each endthereof with suitable means, such as annular flanges 63, one or both ofwhich may be removable, (see Fig. 9,) to prevent the detachment ordisplacement of the sleeve relatively to the weight B. It will beunderstood that this sleeve may be supported by the weight in anysuitable way rather than by having it extend through the longitudinalbore 36 thereof. Adjustable within this sleeve member 60 is a suitablemember in the nature of a rod or bar 6%, having a transversely-extendingpin 65, preferably adjacent to one end thereof and extending into theslot 61 of the sleeve 60, whereby said barand sleeve are splinedtogether for simultaneous rotation and whereby one member is adapted toslide relatively to the other. The pin also prevents the separation ofthe parts 00 and 64:, which constitute the telescopic lampcarryingmeans.

According to one form of means for clamping the sleeve member 60 of thelamp-carrying means adj ustably within the weight a suitablesupplemental sleeve 65 is provided, (see Fig. 3,) preferably splitadjacent to one end thereof, and which sleeve, if desired, may besoldered or otherwise connected at one part or end thereof to the weightto prevent displacement. This sleeve 65 is engaged by the clampingdevice 62, wherebyit will tightly clamp the sleeve member 60 in itsadjusted positions. It will be however un derstood that the supplementalsleeve 65 can be dispensed with, if desired, and the holding member 0 bedirectly clamped by the setscrew 62.

Any suitable means may be carried bythe transversely-ad j ust-ablelamp-carrying memher 0 for holding or supporting a fixture or lamp; butin the presentconstruction, which is shown adapted to support anincandescentlight globe or bulb 100, the member 64: of the carryingmeans C is provided at its outer end with a clamping device in thenature of a pair of spring-arms (50, adapted to spring around thelamp-socket and which arms are pivotally secured at their inner endsadjacent to the end of the member 64 for swinging movement or adjustmentrelatively to the lamp-carrying member 0, and for this purpose the armsare shown bifurcated, as at 67, to preferably receive the end of saidbar or rod 64, which is provided with an enlarged or squared end 68 forthis purpose, integral therewith or detachably secured thereto, asdesired, by a fastening device 68. A suitable pivot device or screw 69extends through the bifurcated ends of said clamping-arms and theenlarged end 68 of the rod or bar 64, and which pivot-screw can be inthe nature of a set or thumb screw, if desired.

According to another form of means for holding an incandescent-lightlamp a screwthreaded stub or member is inserted intermediate thespring-arms 66, at the inner ends thereof, and has a slot 71 openinginto such spring-arms, whereby when it is desired to support the lamp bythe incandescent-light conductor or cord rather. than by the socketthereof such cord may be slipped into said stud or member. (See dottedlines, Figs. 2, 4, and 16.) V

In the use of this improved device the pendulous supporting or holdingmember A, having been attached to a ceiling, or, if desired, to a sidewall,by means of a suitable extending arm or bracket, the weight B issecured thereto by the means herein shown and described and the lampsupporting or carrying member C placed in position relatively to theweight and the lamp placed on said carrying member 0. hen it is desiredto adjust the lamp up and down, the fastening device 26is manipulated topermit the sleeve 24 to be moved relatively to the member 19 of theweight supporting or holding means A and is then reclamped in position.

If an ordinary lamp or a lamp without a shade is used, for instance, thesupplemental weight 35 is moved inwardly toward the pendulous weightsupporting or holding means A and the main weight adjusted, in someforms of construction, on the adjustable bar or arm 46 to bring saidmain weight into effective position to equalize the weight of the lampwhen the lamp-carrying means 0 is adjusted to its extreme position.These bars or arms 46, when detachably secured to the weight, may be ofdiiferent lengths, if desired, according to the different sizes of lampsto be used. The weight of the lamp having been properly equalized by theposition of the main Weight, if it is desired to adjust thelamp-carrying means 0 transversely of the weight, for instance as shownin Fig. 2, the weight bar or arm 46 is moved transversely of thependulous supporting or suspension means A, whereby the weight will bebrought, in this particular adjustment, practically directly under suchpendulous supporting means and will thus equalize the weight of the lamp100 in its adj usted position. From this illustration it will thus beseen that difierent positions of the lamp-carrying means 0 and lamp 100can be quickly and easily secured and the lamp thereby maintained inperfectly horizontal position by moving the weight and its bar or armtransversely of the pendulous supporting means A. It will also beobvious that the Weight bar or arm 46 could remain stationary and theweight be adjusted thereon toward and from the supporting means A, ifdesired, and thereby accomplish the same purpose; but this adjustmentwould necessitate the manipulation of both fastening devices 51 and 62and is therefore not intended for this purpose; but the adjustment ofthe weight on the bar or arm is simply for the purpose of equalizing theweight of the lamp when said lamp is first placed in position inconnection with this improved bracket.

When a heavier lamp is to be carried by this improved lamp-bracket or ashade is placed on the lamp, (which would thereby cause the lamp, withthe additional weight of such shade, and also the weight and thelampcarrying means 0, to assume the position shown in dotted lines, Fig.4,) in order to properly equalize the lamp with its increased weight andbring it into its proper horizontal position it is necessary to augmentor increase the efficiency or effectiveness of the main weight, and todo this the supplemental weight 35 is moved away from the perpendicularor pendulous supporting means A, whereby the lamp-carrying means G willbe again brought into perfectly horizontal position, as shown in fulllines in Fig. 4. This selfsame adjustment, however, may be alsoaccomplished, in some forms of weight, by moving the main weight with oron its bar 46 a greater distance laterally from or transversely to thependulous supporting means A, and thus leaving the supplemental weightfor use in connection with even larger or heavier lamps, or vice versa,unless such adjustments had already been utilized.

When it is desired to bring the lamp into a different position from thatin which it ordinarily hangs, the lamp-carrying means 0 may be rotatedrelatively to the weight by releasing the clamping device 62 and therebyturning the lamp into any desired position-such, for instance, as shownin Fig. 13-and, if desired, a suitable adjustable and removablereflector 90, which may be the subject-matter of a future application,may be used to reflect the rays of said lamp, such a reflector beingshown in the nature of a suitable shield 91, having a spiral or coiledspring 92, adapted to extend around the neck of the lamp-bulb and bymeans of which the shade is held in position.

If it is desired to swing the lamp into various positions up and downindependently of the up-and-down adjustment of the supporting means A,such adjustment can be accomplished by moving the spring-arms 66 intodifferent positions, as shown, for instance, in Figs. 13 and 16, inwhich adjustment the character of shade herein shown is particularlyapplicable.

From the above it will be seen that the lamp -carrying means 0 isadjustable as a whole transversely of the weight, or one member thereofonly may 3e adjusted relatively to the other, either to bring the lampinto a different lighting position or to com pact it into a small spacewhen not in use.

By means of this improved construction of bracket or lamp-supportingmeans the lamp may be adjusted up and down by two separate andindependent adjustments and may be adjusted transversely to itspendulous su pporting means, and in a circular horizontal direction, andin a circular direction at right angles to its transverse adjustment,and different sizes and weights of lamps and their attachments can beused with the same supporting means, and the same, by means of thetelescopic weight-supporting means A and the telescopic lamp-carryingmeans 0, placed in a small space and out of the way, so that by thissimple and inexpensive construction of lamp-bracket an adjustment of thelamp in all. directions can be secured and also a de vice pleasing inshape and design, as Well as a highly-ornamental fixture or article offur niture obtained.

It will be obvious and understood that the various details of thisimproved lamp-bracket or supporting meanssuch, for instance, as thecoupling means-can be greatly varied without departure from the scope ofmy invention, the main features of this device comprising, separatelyand combined, the main and supplemental weights and the variousadjustments thereof and the adjustable pendulous suspension member andlampcarrying member.
